Technical Field
[0001] This invention relates to the field of oral liquid sealing technology, specifically to an automatic sealing device for oral liquid filling. Background Technology
[0002] Oral liquid formulations are widely used in the pharmaceutical and health product industries, and their packaging typically uses glass or plastic bottles sealed with aluminum caps. Currently, the sealing of oral liquids after filling often employs a spinning sealing device, where a die presses threads onto the cap surface to match the bottle neck threads, achieving a seal. However, in actual production, the die is prone to wear or deformation over time, leading to problems such as incomplete thread pressing, insufficient depth, or localized bulges on the cap. This severely affects the sealing quality, potentially causing leakage or contamination, and reducing the product qualification rate. Summary of the Invention

Detailed Implementation
[0035] Please see Figures 1-13 The present invention provides a technical solution: an automatic sealing device for filling oral liquid, including a frame 1, a frame 2, a base 3, and conveyor belts 4 symmetrically distributed on the left and right sides of the base 3. A turntable 5 for conveying oral liquid bottles is fixedly connected to the upper end of the output shaft of the base 3. Multiple pressing mechanisms for pressing the threads of bottle caps are installed at the bottom of the frame 1. A loader 6 for loading bottle caps onto the oral liquid bottles is installed on the frame 2.
[0036] A drive component 7 is fixedly connected to the output position of the turntable 5 on the frame 1. A frame 3 8 is fixedly connected to the bottom of the output shaft of the drive component 7. Two connecting frames 9 are installed at the bottom of the frame 3 8 in a symmetrical arrangement. A detection rod 10 for detecting the integrity of the bottle cap thread is provided on the connecting frame 9.
[0037] The frame 38 is equipped with a detection mechanism, which is used to detect the integrity of the bottle cap thread through two detection rods 10 when the drive component 17 is running and rotating.
[0038] The frame 1 is equipped with a drive mechanism. When the detection mechanism detects that the bottle cap thread is incomplete, the drive component 7 is reset and the drive mechanism drives a new set of pressing mechanisms to change to the pressing station.
[0039] During operation, the two conveyor belts 4 and the base 3 are started. The left conveyor belt 4 transports the filled oral liquid bottles to the base 3. The base 3 drives the turntable 5 to rotate, causing the oral liquid bottles to pass through the positions of the loader 6, the pressing mechanism and the detection mechanism in sequence. Then the right conveyor belt 4 transports the sealed oral liquid bottles away.
[0040] When the bottle body moves to the position of the loader 6, the loader 6 is started to put the bottle cap on the bottle body; when the turntable 5 moves the bottle body with the bottle cap on to the pressing position of the pressing mechanism, the pressing mechanism is started at this time. The pressing mechanism presses the bottle cap and the bottle body together and starts to press the threads on the outside of the bottle cap. The pressed threads are exactly matched with the threads of the bottle mouth. At this time, the bottle cap completely seals the bottle mouth, and the oral liquid bottle is sealed.
[0041] Since bottle caps are usually made of aluminum, they require a large pressing strength and force when pressed. After long-term use, the pressing component itself will inevitably wear and be damaged. At the same time, the connecting parts of the pressing component will also bend, which will lead to incomplete pressing of the bottle cap threads or insufficient pressing depth. This will result in poor sealing effect of oral liquids and may even lead to leakage.
[0042] When the pressing component is damaged, the thread depth on the bottle cap will be shallow or there will be a partial protrusion. When the turntable 5 moves the bottle body with an incomplete seal to the bottom of the drive component 7, the drive component 7 is activated. The drive component 7 moves the frame 8 downward, the frame 8 moves the two connecting frames 9 downward, and the connecting frames 9 move the detection rod 10 downward. When the detection rod 10 moves to the position directly opposite the threaded part on the bottle cap, the drive detection mechanism moves the detection rod 10 to stick to the bottle cap. Then the drive component 7 is activated to move the detection rod 10 downward along the thread on the bottle cap. When the thread depth is insufficient or there is a protrusion, the detection mechanism can detect it based on the position of the detection rod 10.
[0043] After the testing is completed, the testing rod 10 is disengaged from the bottle cap. The driving component 7 drives the frame 8 to reset. After the driving component 7 resets, the driving mechanism drives a new set of pressing mechanisms to move to the pressing position to replace the damaged pressing mechanism.
[0044] This device can automatically detect and replace damaged pressing parts in a timely manner, which can effectively improve the yield rate of oral liquids.
[0045] See Figure 9-11 , Figure 13 As a further embodiment of the present invention, the detection mechanism includes a motor 11 fixed on the frame 8, a lead screw 12 fixedly connected to the output shaft of the motor 11 and rotatably disposed inside the frame 8; two connecting frames 9 are slidably connected to the frame 8 and threadedly connected to the lead screw 12, the lead screw 12 having self-locking properties; a moving component is provided at the bottom of the connecting frame 9, the moving component being used to drive the detection rod 10 to move away from the bottle cap relative to the connecting frame 9 when the detection rod 10 detects that the bottle cap thread is incomplete;
[0046] The moving assembly includes a push block 13 fixedly connected to the end of the detection rod 10 away from the bottle cap; a spring 14 is sleeved on the detection rod 10, with both ends of the spring 14 fixedly connected to the push block 13 and the connecting frame 9 respectively; a push frame 15 is provided between the push block 13 and the connecting frame 9, and a cylinder 16 fixedly on the connecting frame 9 is provided on the upper side of the push frame 15, with the telescopic end of the cylinder 16 fixedly connected to the push frame 15; the push frame 15 is in contact with the push block 13 and the bottom end of the contact portion of the push frame 15 is angled; a one-way sliding unit is provided on the push block 13, which is used to restrict the detection rod 10 to slide only away from the bottle cap relative to the connecting frame 9 when the detection rod 10 is detecting;
[0047] During operation, when the bottle moves below the drive unit 7, the drive unit 7 is activated, causing the frame 8 to move downwards. The frame 8, through two connecting brackets, drives the two detection rods 10 downwards respectively. When both detection rods 10 are aligned with the threaded part on the bottle cap, the cylinder 16 is activated, causing the pusher 15 to move downwards. When the pusher 15 moves upwards, it disengages from the push block 13. At this time, the detection rods 10 move towards the bottle cap under the action of the spring 14. Under the action of the spring 14, when the detection rods 10 reach their limit position, they are exactly in contact with the deepest part of the threaded part on the bottle cap. At this time, the drive unit 7 drives the frame 8 to rotate and move downwards, and the frame 8 will drive the two detection rods 10 to fit against the bottle cap and move downwards along the thread.
[0048] After the detection rod 10 has completed the threaded section, the starter motor 11 drives the lead screw 12 to rotate. The lead screw 12 then drives the two connecting brackets 9 to move away from each other. The two connecting brackets 9 then disengage the two detection rods 10 from the threaded section on the bottle cap. At this point, the starter drive component 7 can move the two detection rods 10 upwards to reset. When the drive component 7 moves the detection rods 10 to the top position, the starter motor 11 can then reset the two connecting brackets 9.
[0049] See Figure 10-12 As a further embodiment of the present invention, the unidirectional sliding unit includes two symmetrically distributed connecting rods 17, each rotatably connected to the push block 13. The other end of each connecting rod 17 is provided with a fixing plate 18 fixed to the connecting frame 9. A sliding frame 19 is provided on the side of the fixing plate 18 away from the bottle cap. Two lead screws 20 are fixedly connected to the sliding frame 19. The lead screws 20 are self-locking, and both lead screws 20 are slidably connected to the fixing plate 18. A sliding plate 21 is slidably connected inside the sliding frame 19. The sliding plate 21 is rotatably connected to the connecting rods 17, and multiple rubber sheets 22 are fixedly connected to the side of the sliding plate 21 closest to the fixing plate 18. The rubber sheets 22 are inclined, and their inclination direction is consistent with the inclination direction of the connecting rods 17 on the same side. A bonding unit is provided on the connecting frame 9. The bonding unit is used to drive the sliding frame 19 to bring the multiple rubber sheets 22 into contact with the fixing plate 18.
[0050] The bonding unit includes a sliding frame 23 slidably connected to the connecting frame 9, a spring 24 fixedly connected to the sliding frame 23, and the upper end of the spring 24 fixedly connected to the connecting frame 9; a toothed ring 25 is sleeved on the lead screw 20, the toothed ring 25 is rotatably connected to the fixing plate 18 and threadedly connected to the lead screw 20; a rack 26 meshes on the rack 25, and multiple racks 26 are fixedly connected to the sliding frame 23; the push frame 15 is located directly below the sliding frame 23 on the side near the connecting frame 9.
[0051] During operation, when the detection rod 10 needs to be driven to contact the bottle cap for detection, the starting cylinder 16 first drives the pusher 15 to move upward. After the pusher 15 disengages from the pusher block 13, the detection rod 10 then contacts the threaded part on the bottle cap under the action of the spring 14. As the cylinder 16 drives the pusher 15 to continue moving, the pusher 15 begins to push the sliding frame 23 to move upward. The sliding frame 23 drives the four racks 26 connected to it to move upward. The four racks 26 drive the four gear rings 25 to rotate. When the gear rings 25 rotate, they drive the sliding frame 19 to move closer to the fixed plate 18 through the lead screw 20. The sliding frame 19 then drives the sliding plate 21 and multiple rubber sheets 22 to gradually approach the fixed plate 18. When the rubber sheets 22 are in contact with the fixed plate 18, the cylinder 16 can be stopped.
[0052] During testing, when the thread depth on the bottle cap is shallow, the travel distance of the detection rod 10 when it moves to the position where it fits the bottle cap is short. After the detection rod 10 finishes testing and is separated from the bottle cap, the friction between the rubber sheet 22 and the fixing plate 18 can just overcome the elastic force of the spring 14, thus keeping the detection rod 10 stationary.
[0053] When there is a protruding part on the threaded part of the bottle cap, when the detection rod 10 is detected, the protruding part will push the detection rod 10 to move away from the bottle cap. When the detection rod 10 moves, it will pull the sliding plate 21 and the rubber sheet 22 to move closer to the detection rod 10 through the connecting rod 17. When the detection rod 10 passes the protruding part, under the friction of the rubber sheet 22 and the fixing plate 18, the detection rod 10 cannot be reset and will remain in that position.
[0054] Both of these situations will increase the distance between the push block 13 at the end of the detection rod 10 and the connecting frame 9. In other words, compared with a normally processed bottle cap, the distance between the two push blocks 13 will increase after the incompletely processed bottle cap is tested.
[0055] See Figure 4 As a further embodiment of the present invention, the pressing mechanism includes a rotating component 27 rotatably connected to the frame 1, a driving component 28 symmetrically fixedly connected to the rotating component 27 at the front and rear positions, and a plurality of rolling blades 29 fixedly connected to the output end of the driving component 28; the output shafts of the driving component 1 and the driving component 28 both have telescopic and rotational functions.
[0056] During operation, the drive unit 28 drives multiple cutting blades 29 to move downward and rotate. After the cutting blades 29 are in contact with the bottle cap, they can press out threads on the bottle cap that match the threads on the bottle mouth.
[0057] When one set of rolling cutters 29 is damaged, the drive rotating component 27 can rotate half a turn to replace a new set of rolling cutters 29 with the pressing position.
[0058] See Figure 3-4 , Figure 7-8 As a further embodiment of the present invention, the driving mechanism includes a sliding frame 2 30 slidably connected to the frame 3 8. The bottom of the sliding frame 2 30 is located above two push blocks 1 13 and two push blocks 2 31 are fixedly connected to it respectively. The distance between the two push blocks 2 31 is greater than the distance between the two push blocks 1 13. A fixed ring 32 is rotatably connected above the sliding frame 2 30. The fixed ring 32 is fixedly connected to the frame 1 1 through two telescopic frames 33. A driving assembly is provided on the fixed ring 32. The driving assembly is used to drive the turntable 5 and the rotating component 27 to rotate 90 degrees and 180 degrees respectively when the fixed ring 32 rises.
[0059] The drive assembly includes a fixed frame 34 fixed on the frame 1, a sliding frame 35 slidably connected to the fixed frame 34, and connecting rods 36 symmetrically rotatably connected to the left and right ends of the sliding frame 35. The other end of the connecting rods 36 is rotatably connected to the fixed ring 32. A rack 37 is fixedly connected to the sliding frame 35. A gear 38 is provided at the coaxial position on the upper end of the turntable 5. A one-way bearing 39 is connected between the gear 38 and the turntable 5, and the gear 38 meshes with the rack 37. A drive unit is provided on the upper end of the gear 38. The drive unit is used to drive the rotating part 27 to rotate when the gear 38 is driven by the rack 37.
[0060] The drive unit includes a pulley 40 and a pulley 41 rotatably connected to the frame 1. The pulley 40 is fixedly connected to the rotating part 27. The pulley 41 is connected to the gear 38 through a one-way bearing 42. The pulley 40 and the pulley 41 mesh together with a belt 43. The diameter of the pulley 40 is half the diameter of the pulley 41.
[0061] The rotational directions of one-way bearing 39 and one-way bearing 42 relative to turntable 5 and pulley 41 are both clockwise.
[0062] During operation, when the rolling cutter 29 is damaged, the thread of the processed bottle cap is incomplete. After inspection, the distance between the push blocks 13 on the two detection rods 10 increases. At this time, the drive component 7 is activated to move the two detection rods 10 and the two push blocks 13 upward to reset. Because the distance between the two push blocks 13 increases, when push blocks 13 move upward, they will contact push block 31 and push the sliding frame 30 upward through push block 31. The sliding frame 30 then drives the fixed ring 32 upward. When the fixed ring 32 moves upward, it drives the sliding frame 35 backward through the two connecting rods 36. The sliding frame 35 drives the rack 37 backward. When the rack 37 moves backward to the position of meshing with the gear 38, it starts to drive the gear 38 to rotate counterclockwise. When the gear 38 rotates counterclockwise, it drives the turntable 5 and the pulley 41 to rotate counterclockwise through the one-way bearing 39 and the one-way bearing 42, respectively.
[0063] When the drive component 7 moves upward to the initial position, the gear 38 rotates exactly 90 degrees, and the turntable 5 and the pulley 41 rotate 90 degrees. When the turntable 5 rotates 90 degrees, it can just drive the bottle cap that has been inspected but not fully processed to move back to the pressing position.
[0064] When pulley 41 rotates 90 degrees, it can drive pulley 40 to rotate 180 degrees through belt 43. Pulley 40 drives rotating component 27 to rotate half a turn. Rotating component 27 then drives the damaged multiple sets of rolling cutters 29 to rotate to the rear and rotates the new multiple sets of rolling cutters 29 to the front pressing position.
[0065] When the driving component 28 drives the new multiple sets of rolling cutters 29 to run, the bottle cap that has not been fully processed can be pressed completely again;
[0066] When the drive component 7 moves the detection rod 10 downward to perform the detection on the next side, the rack 37 moves forward to reset. When the rack 37 resets, it drives the gear 38 to rotate clockwise. Under the action of the one-way bearing 39 and the one-way bearing 42, the clockwise rotation of the gear 38 will not affect the rotation of the turntable 5 and the pulley 41.
